Tree-shaped insulated designs for the uniform distribution of hot water over an area

Design with Constructal Theory

“…Urban design means flow (life) and the performance of its flow structures is robust. Here we illustrate the robustness with an example from the distributing of hot water over an area [18,19].…”

“…The water flow is from one point (the source) to an area-the large number of users spread uniformly over the area. [18]. The search for the flow architecture is guided by two objectives simultaneously: (i) minimum global flow resistance, or pumping power, and (ii) minimum total loss of heat from network to ambient.…”

“…The abscissa indicates the dimensionless insulation volume, defined in Ref. [18]. The number N 0 is the number of heat loss units, defined as 0…”

Effect of Reverting Channels on Heat Transfer Performance of Microchannels with Different Geometries

“…Thus, it develops and evolves over time. The wide application of this theory has not been limited to heat transfer field, and it has been used in different fields such as fluid flow Wechsatol et al (2001) and Gosselin et al(2005), power distribution Arion et al (2003), transportation Bejan et al (2007) and biology Heitor et al (2006) and Bejan et al (2010), etc. Pan et al (2015) experimentally studied and optimized different structures of microchannels used in methanol steam reactor.…”

Morphing tree structures for latent thermal energy storage

“…2,3 The evolutionary designs that emerge naturally are tree-shaped when the tendency of the flow is to flow more easily between areas (or volumes) and discrete points. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] An important contemporary application of the tree-shaped design is in the energy storage systems. [19][20][21][22] The fundamentals of heat transfer in phase change material (PCM) have attracted considerable attention because of the potential use of phase change processes in energy storage applications.…”
